(54) DISPLAY PANEL AND DISPLAY DEVICE


(57) A display panel is provided, including: a first display area (AA1), and a second display area (AA2) at least partially surrounded by the first display area (AA1) and including a plurality of light-transmitting areas (TRA). The display panel includes: a base substrate (1); a plurality of first repeating units (P1) arranged on the base substrate (1) in an array in a row direction and a column direction and located in the first display area (AA1), where each of the first repeating units (P1) includes at least a first sub-pixel (SP1); a plurality of second repeating units (P2) arranged on the base substrate (1) in an array in the row direction and the column direction and located in the second display area (AA2), where each of the second repeating units (P2) includes at least a second sub-pixel (SP2), a color of light emitted by the first sub-pixel (SP1) is the same as a color of light emitted by the second sub-pixel (SP2), an area between two second repeating units (P2) adjacent to each other in the plurality of second repeating units (P2) is the light-transmitting area (TRA), and the plurality of light-transmitting areas (TRA) and the plurality of second repeating units (P2) are alternately arranged along both the row direction and the column direction. The display panel further includes a plurality of spacers which include first spacers (PS1) in the first display area (AA1) and second spacers (PS2) in the second display area (AA2), and a distribution density of the first spacers (PS1) is greater than that of the second spacers (PS2).
